SPECIFICATION forming' part of Letters Patent No. 230,957, dated August 10, 1880.

Application filed June 7, 1880.

To all 'w/Lom it may concern:

Be it known that we, GoRDoN MOKAY, of Cambridge, Middlesex county, and VILLIAM L. TOBEY, of Lawrence, Essex count-y, State of h/Iassachusetts` have invented an lmprovement in Nailing-lVIachines, (Case 13,) of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to mailing-machines chietly for boot and shoe or leather work; and our invention is shown as embodied in that class of mailing-machine wherein the nails employed are those lknown as string-nails, held upon a suitable reel.

feeder of pecnliar shape to engage and feed forward into driving position each nail of the string, forcing the point of each nail against a Curved surface, preferably made as a spring,

zo and called by us a nail-controller7 that gradually tnrns it down from an inclined into a substantially Vertical position, directly in the driver-passage, in line with the (iriver; and, as herein shown, we have arranged a separate .25 eutter'to sever each nail from the string of nails just before it is struck by the driver to be driven. The driver at each descent opera-tes in succession first the feeder and then the cutter. Before the cutter is operated the feeder is released and moved backward by a spring` out ofthe way of the descending driver. The cutter is also lnoved forward and backward between the time the d river is descending from its higliest position to the point where 3 5 the driver meets the nail to be driven by it.

Figure l represents, in vertical section and side elevation, a nailing-machine containing our invention; Fig. 2, a detail thereof, showing the (iriver forced down far enough to act- 40 nate the cutter; and Fig. 3, a detail, showing` the (iriver completely down, and as having driven a nail into a piece of leather or other material below the nose.

The frame B has cars b to hold the usual reel D2. The driver-bar O has a spring, c', to lift it, and at the lower end of the said bar is the driver 02.

The nose d of the machine has located or placed within the driver-passage a nail-controller, dz, made as a curved spring, against In this our present invention we ei'nploy a' (No model.)

which the point of the nail 2 next to be driven is forced by the feeder e as it is made to feed that nail and the string of nails forward, the said controller, by its action on the said nail, turning it downward from the level of the other nails into the position shown in Fig. 1, and holding` it there until struck by the driver.

The feeder e is made as an irregularly-slotted lever, guided on a fulcrum-pin, 82, pulled upward by a spring, 03, and forced down into the position shown in dotted lines, Fig. 1, by the projection 12 at the right-hand side of the driver-bar. At one side of the frame is the lever f, pivoted at fz, provided at its lower end with the cutter g. This lever is acted upon by a spring, (/2, that keeps the upper end of the said lever pressed toward the driverbar and the cutter drawn back, as in Fig. 1.

Just before the driver in its descentreaches the position in Fig. 2 the feeder has acted to 7o feed a nail forward, leaving it in the driverpassage of the nose, as in Fig. 1, and as the projection -LL meets the upper end of the cutterleverfit turns the latter lever and causes the cutter g to sever the nail then in the driverpassage from the string of nails. As the projection 4 passes below the upper end of the lever j' the spring (/2 acts quickly to retract the cutter into the position Fig. 3, and the driver-bar and driver continue to descend' and So drive the nail into the material h, as indicated in Fig. 3.

The slot in the feeder is of such shape as to perlnit the feeder to move in the proper direction backward and forward and carry the nail- 8 5 string along over the inclined surface on which the back of the nail-string rests.

In another application (Case A, filed concurrently with this) we have shown and claimed the nail-controller, and do not therego fore broadly claim the said Controller in this application.

Ve claim- 1. In a nailing-machine, the driver and the driver-bar provided with the projections 12 and 4, combined With a feeder to feed forward string-nails, and an independently-operated cntter to sever the nails from the said string, both the feeder and cutter being operated suc` cessively and independently during each de- Ioo from the string of nails the nail to be driven by the driver, substantially as set forth.

3. In a nailing-maohine, the drivenbar provided with projeotions to operate both the independent feeder and outter, combined With thetsiotted nail-feeder e and the lever and its cutter g, and the nose to keep in its pas- 15 Sage the nail to be driven, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two snhscribing witnesses.
